A=asserted, N=negated
5.7.2 Direction
This register is read/write.
5.7.3 Access Restrictions
This register shall be accessed for host PIO data transfer only when DRQ is set to on and DMACK- is not asserted.
The contents of this register are not valid while a device is in the Sleep mode.
5.7.4 Effect
PIO out data transfers are processed by a series of reads to this register, each read transferring the data that follows the previous
read. PIO in data transfers are processed by a series of writes to this register, each write transferring the data that follows the previ-
ous write. The results of a read during a PIO in or a write during a PIO out are indeterminate.
5.7.5 Functional description
The data port is 16-bits in width. When a CFA device is in 8-bit PIO data transfer mode this register is 8-bits wide using only DD7 to
DD0.
